Sock eating monsters
Peter suspects that the laundromat has sock-eating monsters, as he loses \(25\%\) of his socks when he does laundry each month. If he has 64 socks in the start of January, how many socks does he have at the end of March?
Details and assumptions
Peter does laundry once in January, once in February and once in March. Each time that he does laundry, he brings all of his clothes to the laundromat.
